Specification of Letters Patent.

Application filed November 9, 1912. Serial No. 730,329.

T 0 all whom it may concern Be. it known that I, JOSEPH N. Weiss, a citizen of theUnitcd States, and a residentof Baltimore, in the State of Maryland, ha e invented certain. new and useful lmprovcments in Collapsible Cartons, of which the following is a specification. I

This invention relates to collapsible can tons, more. particularly to the type of carton which is adapted for use as hatl)OX or some similar box Wl ich is adapted for packing an article having considerable bulk.

Boxes or cartons of the above description have been hitherto constructed in'three sec tions, 3 top, bottom and middle section, the latter being collapsible. and when shipped is inserted within the top and bottom sections, the latter telescoping over one another to form a low box in which the middle section may be held. However, this form of collapsible box is not very economical in space in knockdown condition, inasmuch as'thc top and bottom are permanently up and occupy considerably more space than is necessary for the amount of actual material used in their construction. Moreover. these boxes as hitherto constructed do not. fit very snugly when set up for the reason that the top and bottom sectiousmust be of different sizes in order to telescope .within one another, and thus when the entire box is set up, the middle section will not fit snugly in either the top or the bottom as the case may be. To overcome these dillicultics, l have devised a. carton of this character formed of aft-still, lightmaterial such corrugated boar-din which all of the three sections are collapsible, so that When the box is shipped, or stored in knoclodown condition, it will occupy no more. room than the actual amount of material used will Warrant, as all of the parts are laid flat one over the other and no idle space is left anywhere.

In carrying out the invention, the top and bottom sections are formed of a single blank which is scored along its lateral and end edges to form side and end. portions. The blank is cut in along the side scores preferably in an oblique direction, so as to form the ends with outwardly flaring lateral edges. When the section is set up, these lateral edges of the ends wedge in tightly against the sides and are thus: held firmly in nlaco, particularly so by reason of the flez ibility of the material adjacent to these lat eral edges of the end portions produced by the SCOl'lflf". tions are thus set up, the middle section moy be opened up and lku'ccd into the bottom section by its cng gemcnt with the inturned flaps. This holds the middle section tightly in place with a snug lit. The top station may then be inserted ovcr the middle SQ-(. ion and will also fit snugly, and thus it box is produced which is firm, rigid and not readily deranged. Moreover, when col lapsed the psi-ts occupy very little space, presenting an cnorrnons saving in space as compared with the bulky carton as set up and. :1 considerable saving in space as compared with the, collapsible carton of this character such as hitherto used and collapsed in the manner above described.

In the accompanying drawing illustrating one embodiment of this invention Figure l is it perspective "lOW illustrating the carton completely set up. Fig. 2 is a perspective view illustrating the bottom. section. Fig. 3 is fragmontul, sectional elevation illustrating the edging effect produced between the middle and bottom sections. Fig. 4 is perspective view illustrating the sections dollapsed lying one on top of another in position for storing or shipping. Fig. 5 is an enlarged frogmcntnl detail view of a corner section of one of the end closures when collapsed to clearly show the oblique edge of the end flap. larged detail view of a corncrof the box as set up to shon tho/material of the box as being corrugated.

The carton consists of. three sections, top and bottom sections 1 and 2 of substantially similar construction and a middle section 3. The constructi n of the top and bottom see tions is illustrated in Fig. 2. The sections are each formed with a body at having sides 5 and ends 6. Tongues 7 extcndjirom the sides and the ends are provided with flaps S which fold over the tongues and Wedge in against the sides. To produce this wedging action. the lateral edges 9 of the flaps 8 are cut obliquely so as to flare outward as illustrated in Fig. 4. These edges are out along the scores l0 formed between the body 4. and the sides the material adjacent these edges thus being rendered flexible so as to more tightly wedge in against the sides. The lllllll i section composed of cmnparntivcly high walls bounded by scores .ll along which the material may bend, tl'iesc Walls being united preferably at one edge by a l'hen the top and bottom scc-' Fig. 6 is a fragmental enstrip of flexible material 12 such as canvas or the like.

When the box is to be set up, the bottom and top sections are manipulated and set up in the form illustrated in Fig. 2 and then the middle section is opened up and set into the bottom ivedging in against the flaps 8 as illustrated in Fig. 3. After the material to be packed is inserted, the top may then be placed over the middle section and wedged in against the same substantially in the same manner as the bottom section.

It Will be seen that when the box is set up, it presents a firm and rigid construction which is not easily deranged and which is as perfectly suitable for its purpose as a non-collapsible box of this type. Moreover, when the box is to be shipped or stored, the portions thereof may be collapsed so as to occupy the minimum possible space required by the amount of material actually used in its construction. c

Having thus described my invention, I claim as new 1. A three part collapsible carton comprising separate collapsible top and bottom sections, and a separate collapsible middle =2, exactly the same internal perimeter and having means wherewith the middle section is wedged and held tightly in engagement.

2. A three part collapsible carton of lcorrugated material comprising separate collapsible top and bottom sections of the same internal perimeter and having sides and end motion, said top and bottom sections being portions, inwardly inclined resilient flaps extending from the end portions, and a separate collapsible middle section adapted to be forced in the top and bottom sections and wedged between said resilient flaps.

3. A three part collapsible carton of corin the top and bottom sections and wedged between said resilient flaps. i

4. A three part collapsible carton of corrugated material comprising top and bottom sections of exactly the same internal perimeter adapted to be collapsed to occupy the space of one thickness of the material, the end portions of said sections having resilient inturned flaps, and a separate collapsible middle section adapted to be forced in said top and bottom sections and wedged tightly between the resilient flaps, the entire box when collapsed and the sections thereof placed one over the other occupying a space corresponding to the thickness of their ma terial.
